Hi!
Check you connection between 2 PICs. Are you using pullups on your SPI lines? Check both PIC. Do they run at right frequency? Try to find faults in hardware first.
Good luck!
Keith and SheraDoug, Thank you!
You replies brought some sense to my problem.
So little as i know round plane is to reduce noise right? + it will make routing easier, but it will increase cost. I feel like i can pass tease two benefits? or should i choose it?
Mainly... What will it change...
Hi,
I have to make a choice that is to take right way, it takes some experience and knowledge. The things i admit to lack at this point. I had drawn simplest amplifier circuit board using plain CAD software back in the old days. The requirements and responsibility is way up high and i do not...
Is is smart move to pick 4 separate parts. Can i find parts that do not require use of MOSFET drivers or any kind of component like resistors or caps.
Due my lack of experience in this area, i would like to hear your opinion on this matter. Does not have to best solution... one that works is...
Thank you once more!
OK, now i believe that i do understand the core of this problem. How bad this short circuit could be? Can i find a simpler solution like applying capacitor to delay signal? OR i do need 2xP and 2xN part?
I promise that i will think it true later.
alexan_e, Thank you!
I appreciate your fix on problem that i never bothered to notice.
It is late atm, so i didnt give it much thought... by your way... by simply re-wiring circuit, now i can add delay_ms(1) to fix issue with moment of short circuit effect. Of it means that most likely i...
Hi!
I have low power DC motor. Full load at 15V is under 200mA.
Signals are coming from MCU.
Atm im liking 2x IRF7105. 1P and 1N type MOSFET array. ~0,5 EUR per part. The problem is that it is avalable only surface mount type.
IRF7105 datasheet...
Hi !
I have moderate size schematic assembled in Proteus ISIS 7.7. ~50+ components some smaller ICs and one 40 pin MCU + 16x2 char LCD + USB.
Goal:
Is to build a prototype PCB. First off prototype (DIY method). Then a print file for mass production.
Purpose of goal:
To test, analyse and...
Hi !
You can use external pin interrupt (ISR), it is triggered by low to high rising voltage signal from IR sensor (edge) or H to L edge (your choice), you can add timer0 functions into ISR function to collect exact time based measures.
Best wishes !
Hi,
---I believe a timer application (calculator) for PIC mcu will help you alot.

----If your not sure about registers and fuse values you might re check datasheet, from my experience, i solved many similar problem by looking into...
Hi!
Iv heard that defying problem makes wanted "things" much more accessible. Since im plain lost on my way to solve a problem, because i feel like im missing more than 1 puzzle piece to get where i want to be.
I will try to tell what i want.
The application is central heating system...
Re: auto tune pid?
I like to see a well formed answer for this question, as im also interested.
The auto-tune means. amplification constants in pid algorithm are change during work flow of device... Changed based on ? ? ? on... time and error, because tease 2 parameters are reason why ur using...
Seems like a job for charge time measurement unit, since 16F84A got none... Use high frequency oscillator and timer on fastest count up rate. Im sure you can find some performance by optimizing program code and maybe rechecking external electronics on input.
FvM is very correct and pointed very practical and smarrt idea.
To use a example. from microchip.
I beaeve all you need to do is to change modulation part of recordable signal source.
I wish you all the best...
If it is not too busy PM progress.

I quess he...
